Objective:
The students will be capable to represent, graph, compare and order real numbers, to find opposites and absolute values, to evaluate expressions containing absolute value
Lesson Plan: 🔗 6.2(B) Lesson Plan
Standards: 6.2.B Identify a number, its opposite, and its absolute value.
Review: Absolute Value
Number Line:
Number Line. On a number line, positive numbers are to the right of zero. Negative numbers are to the left of zero. Zero is neither positive nor negative.
Opposites. Two integers that lie the same distance from the origin in opposite directions.
For example, “-3” (negative 3) is the opposite of “+3” (positive 3).
Both of these numbers (+3 and -3), represent a point that is three units away from the origin.
The additive inverse of a number is the opposite of a number.
Example, the additive inverse of 5 is -5.
Sign. The sign of any number other than 0 is either positive or negative.
Absolute Value: A number’s distance from zero on a number line. Symbol: ||
The absolute value of a number x is written as ∣ x ∣ .
The symbol for absolute value is a vertical bar ∣ on each side of the number.
We can use the number line to compare and order positive and negative numbers.
Going from left to right, numbers increase in value. Going from right to left, numbers decrease in value.
